Laurie Taylor explores The World Service, talking to Marie Gillespie about her study into the role of the diasporic broadcasters at the heart of the BBC's foreign service. Even though the Service has derived much of its creative and diplomatic significance from these men and women, they've been largely absent from academic work and public debate. Professor Gillespie's work brings to light the invisible writers and intellectuals who've been responsible for the BBC's credibility as an international broadcaster. She's joined by Ramy Aly, a Middle Eastern scholar who has studied the BBC Arabic Service, in particular. Also, who decides when someone is a danger to themselves or others? Professor Gillian Bendelow discusses her research into the use of section 136 of the Mental Health Act 1983.Producer: Jayne Egerton.

TWITTER - Laurie Taylor talks to the sociologist, Dhiraj Murthy, about his new book 'Twitter: Social Communication in the Twitter Age'. This form of social media is now a household name, discussed for its role in political movements, national elections and natural disasters. But what's the real significance of this 'electronically diminished turn to terseness' as Murphy describes it? Using case studies including citizen journalism and health, his groundbreaking study deciphers the ways in which Twitter is re-making contemporary life.Also, elite university admissions. Harvard Professor of Education, Natasha Kumar Warikoo, discusses her research into the perceptions of meritocracy and inequality among undergraduates at Oxford University - part of a wider study of students at the highest ranking universities in the United States and Britain.Given the frequent critiques of such universities for admitting low numbers of state school graduates and, more recently, British Afro-Caribbean students, how do their students make meaning of the admissions process? Melissa Benn, writer and education campaigner joins the discussion.Producer: Jayne Egerton.

Slum Tourism - the transformation of impoverished neighbourhoods into attractions for international tourists. Laurie Taylor talks to the sociologist, Bianca Freire-Medeiros, about 'Touring Poverty', her study of Rocinha, a district in Rio de Janeiro which is advertised as "the largest favela in Latin America." She talked to tour operators, guides, tourists and residents to explore the ethical and political questions raised by selling a glimpse into other peoples' poverty. Professor of Tourism Mobilities, Kevin Hannam, joins the discussion. Also, 'eating the world' - the geographer, Emily Falconer, discusses her research into the food driven impulses of backpacking tourists.Producer: Jayne Egerton.
